DC765B

DC765B Evaluation Board is an off-line DC/DC & AC/DC switch-mode power supply (SMPS) that is designed for the consumer market and other similar applications. It is a medium sized evaluation board, measuring less than 7” x 5” x 3”. It has a built-in linear regulator that sets the output voltage, and includes other features such as over-voltage, over-current protection and thermal management. The DC765B can be used to provide an economical solution to evaluate the performance of AC/DC and DC/DC converters, and also for qualified power applications in computers, monitors, media players, smart phones, tablets, and other handheld devices.

The DC765B Evaluation Board is an integrated SMPS solution that utilizes a combination of high performance switching and linear regulation techniques. It has a two stage topology that includes a voltage mode controlled Switch-Mode PWM (Pulse Width Modulation) regulator and a linear regulator. The PWM regulator consists of a synchronous Boost controller IC, a Power FET and a PWM logic controller. The linear regulator is a high efficiency linear regulator, which is configured to set the output voltage as required.

In operation, the DC765B utilizes the linear regulator to determine the output voltage, and the synchronous Boost regulator and Power FET are used to reduce the amount of switching noise that is generated due to the power conversion process. The PWM logic controller maintains tight regulation of the output voltage by controlling the switching frequency and duty cycle of the series-connected FET. Furthermore, the DC765B includes several features which help to ensure a reliable and robust operation, such as over-voltage and over-current protection.

The DC765B is well suited for applications requiring a low cost and reliable SMPS that can be accurately controlled and monitored. It is an ideal solution for high-end personal computing, multimedia, and communications systems, and for the consumer market. It is also widely used in automotive and the industrial sectors, for applications such as lighting control and battery charging.

In summary, the DC765B Evaluation Board is a low cost, efficient, and reliable off-line DC/DC & AC/DC switch-mode power supply (SMPS) that is designed for the consumer market and other similar applications. It provides an economical solution for evaluating the performance of AC/DC and DC/DC converters, and for qualified power applications in computers, monitors, media players, smart phones, tablets, and other handheld devices. Its linear regulator sets the output voltage and the integration of other features, such as over-voltage, over-current protection and thermal management, helps to ensure a dependable and robust performance.
